Olaf Diegel usually makes 3d printed guitars, but now he made a saxophone.
Saxophone data:
The saxophone has 41 components excluding all the springs and screws, It is printed in nylon, on a SLS machine, and weighs less than a quarter of a real sax (575 grams vs 2.5 Kg. Weight might go up a tad once painted, though, but still a lot less than a metal one).
